Just like yours, children’s skin can be troublesome. Whether that’s a skin condition like eczema or a rash, we know you might be worried about any unusual redness, bumps or dryness on your children’s skin. Here we share the most common children’s skin rashes, what to look out for and what you can do to help.

Whilst many rashes are nothing to worry about, it’s important to seek immediate medical attention if your child also seems unwell and shows any symptoms of meningitis such as a stiff neck, sensitivity to light or a rash that doesn’t fade when a glass is pressed against it.

What causes rashes in children?

From viruses and allergic reactions, to heat and skin conditions there are several common causes of rashes in babies and children. These include:

  • Allergies
  • Insect bites and stings
  • Parasites
  • Chafing or rubbing e.g. nappy rash
  • Bacteria
  • Fungi
  • Viruses
  • Heat
  • Moisture and heat
  • Dribble

Heat rash

Heat and sweat can cause small red, raised spots known as ‘prickly heat’ or heat rash. It can also cause an itchy or prickly sensation as well as mild swelling, and can occur anywhere on the body.

Heat rash can be caused by:

  • Too much exposure to the sun or heat
  • Wearing too many layers of clothing
  • Engaging in intense physical activity

The symptoms of heat rash are similar to that of solar urticaria, an allergic reaction to sunlight. This is a rare condition so unlikely to be the cause of the rash however if symptoms persist, you should consult your GP. If your child becomes overly tired, dizzy, feels sick or has a high temperature, then they may be at risk of heatstroke. In this case, you must seek emergency medical attention as soon as possible.

How to treat children with heat rash?

A heat rash should clear up without treatment but keeping the skin cool can help. Apply a damp cloth or ice pack wrapped in a towel onto the rash and dress your child in loose clothing. Make sure they avoid scratching it as much as possible and only apply suitable creams such as calamine lotion.
